CHURN-OPERATING MECHANISM.

Application filed May 16,

To aZZ w imm t may conce/rfa Be it known that we, (1) .losnrrr Pimm and(2) Cinco. citizens of Czechoslovakia, residing at llvest Fark, in thecounty of Cuyahoga and State ot' Ohio, have invented certain new anduseful Improvements in @burn-Operating Mechanisms, of which thefollowing is a specification.

This invention relates to certain new and useful improvements in churnoperating mechanisms, the primary object of the invention being toutilize in a novel and practical manner the rocking motion of a rockingchair for actuating the reciprocating flange or stirrer of a churn.

Another object of the invention is to provide incased churn operatingmechanism wherein the casing embodies supporting means within the samefor the receptacle of the churn, a suitable floor plate being attachedto one side of the casing that is formed so as to provide a foot rest,and said floor plate being provided with cogs adapted for engagementwith pockets in the rockers of a rocking chair so that when the latteris rocked backwardly and forwardly and operatively connected to theincascd churn operating mechanism, the rockingchair is prevented fromsliding away from the casing and the operation of the churn therebyinsured.

A still further object of the invention is to generally simplify andimprove devices of the present character.

lVith the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists ofthe novel form, combination and arrangement of parts hereinafter morefully described, -shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designatecorresponding parts throughout the several views,

showing the operative connection between the rocking chair and thehorizontal push rod and taken on line IV-IV of Fig. 5,

Fig. 5 is a rear elevational view of the device shown in Fig. L1.

Referring more in detail to the several views, 1 represents a casingpreferably cast in two hollow sections with the lower section open atthe top and closed by means of a. cap or upper section 16 which may beprovided with abutting ianges suitably secured together, the lowersection being provided with a transverse bottom member 19 with acircular flange 19 thereon providing a socket in which the churnreceptacle 2 is seated, introduction of and removal of the churnreceptacle being permitted by leaving the rear of the casing 1 open fora distance at the front as at 35. On the sides of the lower section ofthe casing 1 are formed alined pairs of guide ribs 27 between which theopposite ends of a cross head 5 project whereby said cross head isguided for vertical movements, the ends of the cross head 5 beingarranged as at 28 to prevent undue friction or jamming of the cross headwhen moving between said guide ribs 27, and the upper end of a pistonrod 4 being rigidly attached to the central portion of the cross headrlhe piston rod 4 extends downwardly where it is slidably mounted on thetop of the churn receptacle 2 and is attached to the plunger or strrer 3of said churn, which stirrer may be of any desired specificconstruction.

A pair of ears 5 are formed on the upper side of the cross head 5 asshown in Fig. 3, and a pitman or connecting rod 8 has the lower end ofthe same pivoted to said ears, the upper end of said pitman 8 beingpivoted to the crank portion 10. of a crank shaft 10 which has itsopposite ends journaled in opposite sides of the casing 1 by theprovision of bearings as at 30, which bearings are preferably formed inhalf sections respectively provided on the upper and lower sections ofthe casing at the joint between said sections. A pocket gear wheel 11 issecured upon the crank shaft 10 at one side of the crank portion 10thereof, and the same meshes with a spur gear 12 which is fixed upon atransverse horizontal shaft 29 which is journaled rearwardly of theshaft 10 within the casing 1 in bearings 36 on the sides of said casingwhich are similar to the bearings 30. n- `other spur gear 13 islfastened .upon the shaft 29 and the same meshes with a segment gear V14disposed therebeneath and pivoted as at 15 to the casing substantiallydirectly beneath the shaft 29, an arm 14 being formed integral with thehub of the segment gear 14 and projecting downwardly from the pivot 15whereit is connected slidably and pivotally by means of a pin and slotconnection 18 to the forward end of a push rod 17 which is arranged nearthe bottom of the casing and which is slidabiy disposed through the rearwall of said casing as at 17. The rear wall of the casing 1 is inwardlyoffset near the bottom of the same as at 37 and is then provided with arearward extension as at 38 which forms a foot rest for a personoccupying` the rocking chair 24 as will presently become apparent, thefoot rest 38 being arranged to overlie a portion of the rod 11.

A floor plate composed of an open rectangular frame 21 is disposedrearwardly of the casing 1 and has a flange 21 at forward end suitablyfastened to the casing 1 at the rear of the footrest 38, the side barsof the frame 21 being provided with upwardly projecting teeth 25 whichengage in suitable pockets 25', provided in the rockers of the chair 24.Y

The push rod 17 extends rearwardly and terminates at the rear of thechair 24 where it is connected to the lower end of a lever 39 by a pinand slot connection 40, the lever 39 being centrally pivoted upon ahorizontal axis as at 41 between and to the upper ends of a pair of arms20 which are integrally connected to the side bars of the frame 21. Theupper end of the vlever 39 is pivoted as at 22 to a bracket 23 which isrigidly fas tened to the back of the chair 24, and a spring 26 isfastened to the push rod 17 and bea-rsupon the lever 39 so as toyieldingly resist relative movement of these parts.

1n operation, the parte are disposed as shown in Fig. 1 so that a personoccupying the chair 24 may rest his or her feet upon the foot rest 38and manually cause rocking of the chair in the well known manner. Theengagement ci the teeth 25 with the rockers prevent relative separationof the casing 1 and the rocking chair so that'rock` ing of said chairpositively causes longitudinal reciprocation of the push rod 17 throughrocking of the lever 39. of the push rod 17 oscillates the segment gear14 and this imparts oscillatory rotary motion to the gears 13, 12 and 11and also to the crank 1G. .The pitman 8 and piston rod 4 are accordinglyreciprocated for causing the stirrer 3 to reciprocate withinithereceptacle 2 for churning material therein.l

Sliding movement When the churning Operation has been completed, thecrank 10 may be moved to a ver tical position so that the stirrer 3 androd 4 are withdrawn from the body of the receptacle 2 along' with thecover of the latter. The body of the receptacle 2 may then be removedthrough the opening 35 and after the same is emptied it may be replacedor a new one may be substituted for repeating the operation. Y

By forming theV bearings 3() and 36 in half sections at the adjacentedges of the sections of the casing 1, the parts may be quicklyoriginally assembled or removed for renewal or repair with considerableease. rlhe present construction accordingly pro, vides a simplified anddurable mechanism for the operation of churn-dashers or equivalentreciprocated members and provides for inoasing the, gears and othermovable parts so that the device will havea neat appearance and so thatcatching of the persons clothing in moving parts is rendered un likely.

1t is believed that the construction and operation as well as theadvantages of the present invention will be readily understood andappreciated by those skilled in'the art.

Minor changes may be made in the invention without ,scope thereof. Y

ilhat is claimed as new is 1n a churn operating mechanism, of areceptacle, a member to be actuated disposed within the receptacle,guide strips upon the inner side walls of the receptacle, a crank shaftjournaled within the receptacle and-v adjacent the upperends of theguide strips, a gear wheel keyed to said crank shaft, -a segment gearpivotally mounted within the receptacle, connections between the segmentgear, crank shaft gear and means eX- ternally of the receptacle foractuating said segment gear, 'comprising anV open substantiallyrectangular frame rigidly attached to the receptacle, a memberpositioned for rocking movement upon the frame, vertical bracketscentrally of the frame and adjacent one end thereof, a lever pivotedintermediate its ends to the upper ends of said brackets, said leverbeing pivotally mounted upon the said rocking member and a reciprocatingshafubetween the lower end of said segment gear and the said lever forpurposes specified.
